500A Starting 200A Rated Wireless Battery Disconnect Switch & 4 AWG

In this review of the FEITON remote battery disconnect switch kit, the bottom line is simple: it is best for vehicle owners who want a straightforward, no-modification way to cut battery power remotely to prevent drain and deter theft. The kit combines a 200A rated disconnect with a 500A starting capability and includes 1 ft 4 AWG positive and negative cables, making it a convenient plug-in solution. Installation is generally quick and the build quality feels solid, though a few users noted the wiring instructions could be clearer.

Key Features

• Wireless remote kill switch: Lets the user cut car battery power from a distance to prevent parasitic drain and improve theft protection with a single button press.
• 200A rated switch, 500A starting: Provides a high continuous current rating with a higher momentary starting capacity, suitable for most cars and light trucks.
• 4 AWG pure copper cables: Short 1 ft wires with pure copper inner cores maximize transmission efficiency and reduce voltage drop between battery and switch.
• Durable cable construction: PVC insulated cover, heat shrink sealed ends, and tinned copper lugs resist corrosion and improve long-term reliability in automotive environments.
• No modifications required: The kit is designed for simple inline installation so the user does not need to open the hood repeatedly to isolate power.
• Warranty and support: FEITON includes a 1-year warranty and email support for replacements or questions about the remote disconnect.

Who It's For

This kit is aimed at car and truck owners who want a quick, reversible way to disable their vehicle battery for security or to combat parasitic battery drain. It works well for seasonal vehicles, project cars, or owners who park in areas with theft concerns and prefer a remote on/off solution without complex wiring changes.

It is less suited to someone who needs a fully integrated fleet telematics or keyed master kill solution, or to owners who expect exhaustive printed wiring guidance; a few customers reported the included wiring instructions were not detailed enough, so basic comfort with automotive battery wiring is recommended.
